TRACK -LAYlNG MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 735,457, dated August 4, 1903.

Application filed May 23,1903.

To all whom it mag concern:

of the rail-delivery trams.

Be it known that I, EDWARD J. BRENNAN,

a citizen of the United States, residing at St.

Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in 'lrack-Laying'Ma-- chines, of which the following is a specification.

track-laying machines of that class in which the ties and rails are carried on tramways from the supply-car to where the tracks are being laid; and it consists particularly inproviding unloading and laying means so supported upon the car that a greater number of rails with the supply-car in one position may be laid than with the ordinary construction of track-laying machine.

To this end my invention consists in the features of construction and combination hereinties. The tramway-sections are suitably sea cured together and project some distance beyond the end of the car, as illustrated in Figs. 1 and 2, the tie-delivery trams preferably extending some distance beyond the end Mounted upon the forward end of the car is the derrick-supporting frame 0. As shown in Fig. 1, the

derrick-supporting frame extends a consider able distance beyond the forward end of the car and is supported in position by cables 2, connecting the top of the frame with the rear end of the car. "The forwardly-extending ends of the tramway-seetions are I supported Having rotatable support in the forward end of the frame;

from the frame by cables 3.

O is the derrick-mast 4, carrying a forwardlyextending boom 5, the end of the boom being braced by the cable 6. Mounted upon My invention relates to improvements in Serial No. 158.477. (No model.)

the frame 0 adjacent to the derrick is a windlass 7,- driven from a suitable source of rearwardly from the derrick-mast.

In operation the ties and rails to be used in constructing the track are placed upon the rollers 13 of the tramway-sections and suitably forced forward to the projecting ends of said sections, where the ties are received by the workmen and arranged upon the ground.

The railseetions, as shown in Fig. 2, are received by the hoisting-cables 8 and 10 and by the aetu ating of the Windlass 7 are deposited in position upon the ties. As shown in Fig. 2, the hoisting-cable 1O first deposits a rail upon the ties intermediate of the derrick and the end of the car, and thereafter the hoisting-cable 8 deposits a second rail beyond the derrick and in line with the first rail. Upon the rails being laid upon one side of the track the derrick may be turned to deposit rails to form the other side of the track.

The essential feature of myinvention, it will be noted, is the means for supporting the derrick at aconsiderable distance in front of the end of the ear, whereby the rail-sections may be deposited from the tramways both behind the derrick and in front of the derrick, thus greatly extending the length of track that can be laid in one position of the car.

Having now described my invention, what I claim asnew, and desire to secure by Letters Patent, is-

1. In a track-laying machine of the class described, the combination with its supply-car and tramway-sections supported along the sides of said car, said sections extending beyond the end of the car, of a frameworksupported upon said car and extending beyond the forward end thereof, supporting-stays connecting said framework and-'the projecting end of said tramway-sections, and a derrick mounted upon the forwardcndjof said frame.

2. I11 a track-laying machine of the class described, the combination with a supply-car and tramway-sections supported along the sides of said car and extending beyond the front end thereof, of a frame supported upon said car and projecting beyond the forward end thereof, and a derrick mounted upon the projecting end of said frame.

In atrack-laying machine of the class described, the combination with a supply-car, tramway-sections supported along the sides of said car and extending beyond the front end thereof, a frame supported upon said car and extending beyond the front end thereof, and a derrick supported upon said frame intermediate of theprojecting ends of the tramway-sections, and of the front end of the car.

4. In a track-laying machine of the class described, the combination of a supplycar, tramway-sections supported along the sides of said car and extending beyond the front EDVARD J. BEEN NAN.
